[Freeswitch-users] Packet Loss and Round Trip Time

[Tristan Mahé]

Maybe check the variables rtp_audio_* ?

I can't recall the latency being exposed, but at least MOS is.

I tend also to recall that some rtp stats are written in the xml cdrs,
or if you want some realtime, there's the API command
uuid_set_media_stats to check.

Best,

Tristan.
